This article presents the accurate surface tension measurement of cis-1-chloro-2,3,3,3-tetrafluoropropene (R1224yd(Z), (Z)-CF3CF═CHCl), over the temperature range 266-340 K. The measurement was performed using the differential capillary rise. The expanded uncertainty at 95% confidence was estimated to be within 0.19 mN·m-1. Based on the measured data, the van der Waals-type correlation expressing the temperature dependence was obtained as σ = 57.02 (1 - T/428.69)1.265 [mN·m-1]. In addition, the parachor [PR1224yd(Z)] was determined as 207. The surface tension values predicted by Miller and Thodos (Ind. Eng. Chem. Fund., 1963, 2.1, 78), Miqueu et al. (Fluid Ph. Equilibria, 2000, 172, 169), and Di Nicola et al. (Int. J. Thermophys., 2011, 34, 2243), as well as those obtained using the parachor method, were in good agreement with the measurement data.
